A machine (1) for preparing a beverage from an ingredient includes an extraction unit (2) that has: an ingredient extraction seat (20); an inlet arrangement (21) for guiding water into the seat (20); and a dispensing arrangement (22) for guiding beverage out of the seat (20). The dispensing arrangement (22) has a face (220) delimiting a downstream part of the seat (20) and having a flow-through portion (221) configured such that beverage flowing out the seat (20) flows through the flow-through portion (221) towards a beverage dispensing area (1). The face (220) has a flow-inhibiting portion (222, 222a, 222b, 222c) that is at least substantially flush with the flow-through portion (221) so as to delimit the seat (20). The flow-inhibiting portion (222, 222a, 222b, 222c) is configured such that beverage flowing out the seat (20) is inhibited, e.g. prevented, from passing through the flow-inhibiting portion (222, 222a, 222b, 222c).

The invention relates to a beverage extraction unit (1) for extracting a beverage from an exchangeable single-serve portioned capsule (2) containing beverage ingredients and being configured with a flow restricting member for extracting capsules at different beverage pressure and flow conditions. The invention also relates to the beverage machine comprising the extraction unit.

A capsule processing machine (1) for preparing a beverage from a capsule (5) having a body (50) containing an ingredient. The machine (1) has a holder (10) with a cavity (11) having an upwardly oriented mouth (12) and a cover (20) cooperating with the holder (10). The cover (20) and the holder (10) are relatively movable along a movement path (14) from: an open position for inserting the capsule (5) inbetween the holder (10) and cover (20) into the cavity (11) and/or for removing the capsule (5) therefrom; to a closed position for extracting the capsule (5) in the cavity (11). The machine (1) includes a capsule transfer device (30) having a capsule guide (31) for guiding the capsule (5) from the holder (10) to a used-capsule evacuation area (40). The capsule guide (31) extends along an evacuation direction (31) and is configured to seize the capsule (5) and hold the capsule (5) above the holder (10) and to guide the capsule (5) towards the evacuation area (40) along the evacuation direction (31). The movement path (14) and the evacuation direction (31) are at an angle (1,2,3,4) favouring a movement of the capsule (5) under the effect of gravity along the capsule guide (31) towards the evacuation area (40). The capsule guide (31) is tillable during the relative movement of the holder (10) and the cover (20) from the closed position to the open position to reduce the angle (1,2,3,4) so as to increase the effect of gravity for moving the capsule (5).

An adjustable brew head linkage includes a brew head linkage element, a handle linkage element, and an adjusting element between the brew head linkage element and the handle linkage element to smoothly increase and decrease the distance between the brew head linkage element and the handle linkage element to alter the size of a corresponding brew chamber to accommodate various brew pods. The brew head linkage element and/or handle linkage element may include a threaded portion to engage the adjusting element. Turning the adjusting element causes deflection. Threaded portions may have opposite handedness or different pitches. A secondary brew head linkage locking element provides friction to lock the adjusting element in place. The adjusting element increases and decreases the distance between the head linkage and the handle linkage in increments smaller than 0.178 millimeters ( 7/1000 inches).

A brewing device for a machine for preparing beverages, in particular coffee or tea, in which the brewing device comprising a brewing chamber having a longitudinal axis, a frame having two walls arranged on opposite sides of the brewing chamber, and a fastening device. The fastening device is configured to releasably couple the brewing device to a support body in the beverage preparation machine and comprises a lever release device hinged to the frame to rotate about an axis transverse to the longitudinal axis between a normal coupling position, in which the lever release device stably holds the brewing device on the support body, and a release position, in which the lever release device allows the brewing device to be released from, or mounted on, the support body.

The present disclosure is for an electronic control system for a brewing device for a machine for preparing beverages, in particular coffee or tea. The brewing device comprises a brewing chamber having an opening through which a material to be brewed may be loaded and discharged; a closing body movable away from and towards a sealed closing position of the opening angularly spaced apart from the closing position, through an intermediate ejection position, in which the closing body is raised with respect to the closing position along the longitudinal axis of the brewing chamber; a piston slidably mounted in the brewing chamber in a position axially opposite the closing body; a first electric actuating device for the movement of the closing body; and a second electric actuating device for the movement of the piston. The electronic control system is configured to be arrangeable in the brewing device and comprises a sensory system configured to output electrical signals to allow the reaching, by the closing body, of the opening, closing and ejection positions to be sensed, and the axial position of the piston in the brewing chamber to be determined, and an on-board electronic control unit configured to be connectable to the sensory system to receive electrical signals therefrom, to the first and second electric actuating device to supply electrical control signals thereto, and to an electronic control unit of the beverage preparation machine external to the brewing device to receive therefrom commands relating to the operation of the brewing device. The on-board electronic control unit is further configured to execute commands received from the external control unit to responsively output, also based on the electrical signals received from the sensory system, electrical control signals for the electric actuating devices.

The beverage producing machine comprises a brewing chamber and at least one hydraulic actuator for controlling closing and opening movement of the chamber. A water pump, fluidly connected to the chamber through a first water path and fluidly connected to the actuator through a second water path delivers pressurized water to the chamber and actuator, respectively. A water heater and a first valve arrangement are arranged along the first water path. A second valve arrangement is positioned along the second water path, between the water pump and the actuator. The first and second valve arrangements are configured and controlled such that during a brewing chamber closure step the first valve arrangement is closed, and the second valve arrangement is open. Upon reaching a closure pressure in the actuator, the second valve arrangement is closed and the first valve arrangement is opened, allowing water to be delivered to the chamber.

A motorized beverage machine (1) has: activation means that comprise a motor (3); and a brewing unit (2) that comprises a first assembly (13) and a second assembly (14) cooperating together, each assembly delimiting part of a brewing chamber (29) for containing an ingredient capsule (30). At least one of these assemblies (14) is: movable away from the cooperating assembly (13) into an open position within the machine for forming between the assemblies a passage (31) for inserting into and/or removing from the brewing unit the ingredient capsule; and movable to the cooperating assembly into a closed position for forming the brewing chamber. The motor is a low power motor configured to: generate a maximum torque of no more than 50 mNm; and/or consume a maximum power of no more than 50 W, for driving the movable assembly between the open and closed positions.

The present invention discloses a coffee brewing device, which comprises a brewing head assembly, a powder box assembly, a screw assembly, a body fixing frame assembly, a movable frame assembly and a powder guide box assembly which are correspondingly provided. The present invention realizes the direction-variable movement of the powder box assembly in the movement process, and swings to corresponding positions for adding coffee powder, brewing, pushing out residues, scraping residues and realizing restoration.
